There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.
Command: ["startvm", "d5a36638-a32d-4826-83b7-d7bde5f2069c", "--type", "headless"]
Stderr: VBoxManage: error: VT-x is not available (VERR_VMX_NO_VMX)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ConsoleWrap, interface IConsole
Estou utilizando o Vagrant + virtualbox, rodando dentro de outra virtualbox (fedora) em cima de um Windows 10. Tentei utilizar no Vagrantfile "vb.cpus = 1" , mas não funcionou.
